Abstract This study aimed to detect mycotoxins (aflatoxin B1, ochratoxin A, zearalenone, fumonisin B1 and deoxynivalenol) residues in imported frozen/local fresh chicken muscle and local fresh liver/kidney samples in Jordan. A total of 300 samples composed of 50 imported frozen and 150 locally produced fresh chicken muscle, 50 fresh liver and 50 kidney samples were analyzed. These were examined for mycotoxins using liquid chromatography-mass spectrophotometry (LC–MS/MS). The overall concentrations of mycotoxin residues in the tested samples ranged from 0.03 to 2920.00 μg/kg (mean 0.23–324.24 μg/kg). Zearalenone and aflatoxin B1 exceeding the maximum residue level (MRL) were found in 14 and 2% of the imported chicken muscle samples, respectively. Aflatoxin B1, zearalenone and deoxynivalenol above the MRL were found in 0.7%, 10.7% and 8.7% of local chicken muscle samples, respectively. Zearalenone (>MRL) was the only toxin detected in the local liver samples whereas zearalenone, fumonisin B1 and deoxynivalenol (>MRL) were present in local kidney samples. The results revealed a significant difference in the prevalence of deoxynivalenol between local and imported chicken muscle samples (P
